I only settled on one evil embark. I read about the need to rush underground first and foremost, and then open up to the outside only when you are ready. I brought actual tools and a military dorf+equipment instead of forging stuff next to the wagon. Other than the tools/armor, I even brought large stacks of food that would still fit in a single barrel (like 200 pineapple and 100 eggs as food...only 2 actual barrels).
I lasted maybe a minute. A flock of undead ravens was waiting for me. They immediately swept over the wagon and killed 4 dorfs before my maceman could even finish equipping. The miner had barely started digging when he was chased away. Everyone was dead within maybe a couple game days. So... yeah. Hit or miss.
I thought bringing any livestock is a bad idea until you know fr sure if the biome reanimates or not. Eventually the turkey's will die from old age, so you need to check their ages and occasionally lava toss/atom smash the older ones, right? Also.... why swordsmen? Zombies neither feel pain nor bleed out. If the biome does reanimate, any lost limbs will keep moving on their own. Isn't it a bad idea to start with those over macemen (zombies with no bones and pulped internal tissue can't move if they wanted too).
My original plan was to bring a mechanic and immediately go underground/turtle up. This would only last a couple months, as I planned to find the caverns asap and get some traps going. Before the migrants arrived I'd have a line handful of cage traps and 2 macemen (training the whole time) as "escorts" to make sure the migrants got there in time. For food.. I was planning on those huge barrels with a few (early) years worth of food/booze material to tide me over. 200 fruit in one barrel is just one hauling job (and when tested didn't seem to slow the hauler down). Once I got the trap line up, the "military" trained some more, a "bath" at the entrance to wash off abnormal rain/blood, and hopefully a metal industry running to forge more zombie-repellant (as well as living quarters and hopefully a cistern), I'd get around to a proper food industry (mostly farms and caravan imports). Textiles aren't needed for the first year, but I'd likely just expand the farms and go full pig tails. If the biome was non-reanimating I'd try going into the cavers for silk (instead of raiding it for "wood" only).
One of these days I'll build up the courage to try again... I'm stlll scarred from that immediate raven attack though :S
